Triacylated peonidin 3-sophoroside-5-glucosides were isolated from the purple flowers of Moricandia ramburii Webb. (Family: Brassicaceae), and determined to be peonidin 3-O-[2-O-(2-O-(trans-feruloyl)-glucosyl)-6-O-(trans-p-coumaroyl)-glucoside]-5-O-[6-O-(malonyl)-glucoside] (1), peonidin 3-O-[2-O-(2-O-(trans-feruloyl)-glucosyl)-6-O-(cis-p-coumaroyl)-glucoside]-5-O-[6-O-(malonyl)-glucoside] (2) and peonidin 3-O-[2-O-(2-O-(trans-sinapoyl)-glucosyl)-6-O-(trans-p-coumaroyl)-glucoside]-5-O-[6-O-(malonyl)-glucoside] (3), respectively, by chemical and spectroscopic methods. In addition, one known acylated cyanidin glycoside, cyanidin 3-O-[2-O-(2-O-(trans-feruloyl)-glucosyl)-6-O-(trans-p-coumaroyl)-glucoside]-5-O-[6-O-(malonyl)-glucoside] (4), was also identified in the flowers. Peonidin glycosides have not been reported hitherto in floral tissues in to Brassicaceae.
从紫菀科植物破布叶（Moricandia ramburii Webb.）的紫色花朵中分离得到三酰基矢车菊素 3-槐糖苷-5-葡萄糖苷，并通过化学和光谱方法分别鉴定为矢车菊素 3-O-[2-O-(2-O-(反式阿魏酰基)-葡萄糖基)-6-O-(反式对香豆酰基)-葡萄糖苷]-5-O-[6-O-(丙二酰基)-葡萄糖苷]（1）、矢车菊素 3-O-[2-O-(2-O-(反式阿魏酰基)-葡萄糖基)-6-O-(顺式对香豆酰基)-葡萄糖苷]-5-O-[6-O-(丙二酰基)-葡萄糖苷]（2）和矢车菊素 3-O-[2-O-(2-O-(反式芥子酰基)-葡萄糖基)-6-O-(反式对香豆酰基)-葡萄糖苷]-5-O-[6-O-(丙二酰基)-葡萄糖苷]（3）。此外，在花朵中还鉴定出一种已知的酰化飞燕草素糖苷，即飞燕草素 3-O-[2-O-(2-O-(反式阿魏酰基)-葡萄糖基)-6-O-(反式对香豆酰基)-葡萄糖苷]-5-O-[6-O-(丙二酰基)-葡萄糖苷]（4）。迄今为止，矢车菊素糖苷尚未在十字花科植物的花组织中报道过。
